Named Obj-C Property Getters and Setters in Swift - objective-c

Question

I am looking for a general solution to access:
Obj-C named property getters and named property setters from Swift
Conform to an Objective-C #protocol with readonly properties
Similar to Creating an Objective-C equivalent Getter and Setter in Swift, which is closed, yet does not offer a satisfying answer.
Objective-C to Swift Properties Example:
I have an Objective-C protocol defined with two problematic properties, one with a custom getter isEnabled and another with a private setter exists.
#protocol SomeProtocol <NSObject>
#property (nonatomic, assign, getter = isEnabled) BOOL enabled;
#property (nonatomic, readonly) BOOL exists;
#end
How can I access these Objective-C properties from Swift?
This does not seem to work:
func isEnabled() -> Bool { return self.enabled }
and neither does:
var isEnabled:Bool {
get { }
set { }
}

Straight from the documentation:
Use the #objc(<#name#>) attribute to provide Objective-C names for properties and methods when necessary. For example, you can mark a property called enabled to have a getter named isEnabled in Objective-C like this:
SWIFT
var enabled: Bool {
#objc(isEnabled) get {
/* ... */
}
}
Named Objective-C Getter Property in Swift
var _enabled:Bool = false
var enabled:Bool {
#objc(isEnabled) get {
return self._enabled
}
set(newValue){
_enabled = newValue
}
}
readonly Objective-C Property in Swift
Either
var _exists:Bool = false
private(set) var exists:Bool {
get{
return self._exists
}
set(newValue){
self._exists = newValue
}
}
or
var _exists:Bool = false
var exists:Bool {
get{
return self._exists
}
}
and access self._exists directly since there is no setter.
